For example, if you increase the brightness of a layer that is too dark overall, the finished image will likely have a washed-out appearance. This is because the brightness slider turns the layer’s darkest tones (like black) into medium tones, and so the overall contrast has been reduced. To adjust brightness in a non-uniform manner, you should use the “Curves” menu instead. This will allow you to adjust brightness while preserving the layer’s tonal variety.
